One of the principal problems the Bureau of Indian Affairs (BIA) has in carrying out its responsibility to educate Indian children is the high turnover rate among its teachers; a large proportion of teachers in the BIA school system leave after their first year or second year of work. Teachers at six elementary schools on the Navajo Reservation were interviewed to determine the features they considered rewarding and the drawbacks associated with their place of work. The countryside itself and...

Questionnaires were sent to Deans of Students at Texas community colleges in order to gather information on the international (foreign student) programs at the various colleges. Areas examined included admissions requirements, pre-conditional admissions requirements, and handling of international students subsequent to admission. Of the 46 schools responding to the survey, 39 indicated they enrolled international students. The average number of internationals per institution was 64, with six...

An array of sensors is receiving radiation from a source of interest. The source and the array are in closed three dimensional waveguide. The maximum-likelihood estimators of the coordinates of the source are analysed under the assumptions that the noise field is Gaussian, and the source lies on a finite linear manifold spanned by a set of orthogonal functions. These functions are the eigen-functions of the wave operator given the boundary conditions defining the waveguide, and are called...

A method of using hardware redundancy to ease the problem of fault testing in combinational and sequential logic circuits is presented. Dual-mode logic gates are used to construct combinational logic circuits which can be tested for all single stuck-at faults using just two function-independent tests. Analogous results for sequential circuits are also presented. (Author)

This thesis presents a specification for the Multics virtual memory manager. The virtual memory manager is that part of the operating system which coordinates the usage of physical memory and which manages the bindings between logical memory and physical memory. In the case of Multics, physical memory is composed of fixed-length blocks called frames and logical memory consists of segments, representing sets of frames. The original specification is now obsolete because it describes an overly...

This report describes a theoretical investigation of the oscillatory motions, stability, and orientation of the Moored Body Scheme A in current and waves. Linear, first order equations for oscillatory motions and cable tension, are developed for a body of revolution moored to the bottom in finite depth water by a single restraining cable. Wave exciting forces and certain hydrodynamic coefficients are developed from potential flow theory, and non-linear viscous damping effects are included in...

This study investigated verbal behavior of five third-grade children representing three cultural groups: Afro-American, Afro-Caribbean, and white. Ten sessions involving various language arts activities were tape recorded over a five-week period; session 7 was also videotaped. Sessions 3 to 10 involved group interaction across three interaction patterns: adult-dominated, peer-dominated, and adult-balanced. Results indicated that children produced more complex speech when allowed to interact...

In a hybrid communication system, comprising both satellite and terrestrial networks, part of the network topology is adaptable. The availabiltiy of adaptable topology and alternate routing in such networks provides the designer with considerable freedom to insure satisfactory network and point-to-point grades of service. The complexity inherent in such a design problem is discussed. A heuristic algorithm--which can be implemented on a digital computer--for designing hybrid networks with the...

The objective of this program was to develop a corrosion inhibiting primer suitable for adhesive bonding which can also serve as corrosion protection for detail aluminum parts. The developed primer must be adaptable to an automated application method. The program utilized the electropriming application method and investigated the polyester, acrylic, and epoxy electropriming resins. The anodic and the cathodic electropriming processes were evaluated. The cathodic application was shown to be the...

Two-dimensional 16x24 InSb CID area arrays have been designed and successfully fabricated via a multilayer MIS processing technique. The operation of these arrays in a staring mode has been demonstrated by displaying real time raster-scanned IR images on an X-Y CRT monitor. The raw video image displays were as sharp as the actual objects, being clearly recognizable with no sign of blooming and, therefore, excellent operating characteristic. Theoretical analysis showed that at low sample rates,...

Baseline information on water quality was derived for streams and ponds draining or located on the Eglin Air Force Base Reservation, Florida. The water temperature displayed seasonal trends (mean seasonal range 15.5 C to 22.9 C). The dissolved oxygen (DO) values were inversely related to the water temperature. The mean seasonal DO range was 7.6 ppm to 9.0 ppm. The mean seasonal pH was low, range 5.6 to 5.7, displaying no seasonal trends. Also remaining consistently low and displaying no...

From July through September 1975, a series of ship motion simulation experiments was conducted using the ONR Motion Generator at Human Factors Research, Inc., Goleta, California. The motions were based on the mathematical model for the 2000 ton surface effect ship (2000T-SES). Nineteen volunteer human research subjects, selected at different times from 600 naval enlisted recruits, briefed on NAMRL Detachment research, were exposed to several motion profiles. These subjects were extensively...

Individuals previously identified as language-bound (LB) and language- optional (LO) participated in a series of experiments designed to study verbal fluency. The two groups showed a striking similarity in the number of responses they produced for categories with constraints at various levels (word form, word content, sentence, interpretation). This similarity occurred for both written and oral modes of response, and over a wide range of time intervals. Other types of measures, however,...

This paper examines several image segmentation algorithms which have been explored in the development of the VISIONS system. Each of these algorithms can be viewed as a variation on a basic theme: the clustering of activity in feature space via histogram analysis, mapping these clusters back onto the image, and then isolating regions by analysis of the spatial relationships of the cluster labels. It is shown that the interaction between these two representations of data (global feature...

Of the physical effects that limit the propagation of a high intensity laser beam through the atmosphere, air breakdown has the most catastrophic influence. Completely ionized air attenuates 10.6 micron radiation within a few centimeters. It is therefore imperative that the threshold for air breakdown under realistic circumstances be determined. In this report the physics of long pulse laser-induced breakdown process in particle-contaminated air is studied in four stages. The first stage is...

Film-cooling-air ejection from the pressure surface of a turbine vane was investigated, and experimental data are presented. This investigation was conducted in a four-vane cascade on a J75-size turbine vane that had a double row of staggered holes in line with the primary flow and located downstream of the leading edge region. The results showed that: (1) the average effectiveness of film-convection cooling was higher than that of either film cooling or convection cooling separately; (2) the...
